Endocrine Disruptors in Puget Sound

Irvin Schultz

We’ve done lab work on fish/embryos response to exposure to estrogens, androgens, thryroid active agents (e.g. PBDEs), pychoactive drugs (e.g. Prozac).  Placed fish cages and water sampling by grab & passive equipment at field sites in Bell Creek (dairy farm runoff), Sammamish River (near stormwater outfalls), Tulalip tribal wastewater facility (secondary treatment water in tanks), White River (Enumclaw waste water).


  • detected compounds with both sample methods
  • no response (induction of vitellogenin, fertility reduction via aneuploidy)  from fish, possibly because exposure was too short
